Here's a zoomable 3D model of the world's busiest train station, Shinjuku in Tokyo: https://satoshi7190.github.io/Shinjuku-indoor-threejs-demo/ https://satoshi7190.github.io/Shinjuku-indoor-threejs-demo/ 3.6 million passengers per day. Wikipedia: The main East Japan Railway Company (JR East) station and the directly adjacent private railways have a total of 35 platforms, an underground arcade, above-ground arcade and numerous hallways with another 17 platforms (52 total) that can be accessed through hallways to five directly connected stations without surfacing outside. The entire above/underground complex has well over 200 exits.

3.6m is crazy. That must be a decent % of the entire Tokyo pop.

  Almost 10%. Framed like that it almost seems highly inefficient that so many are routed through this one station in particular. Presumably they could have had more direct routes to their destinations.

    And for context Tokyo is a huge metro. It can be 40 minutes between 2 places directly that any other country would consider cities by themselves. There is no such thing as CBD or downtown here IMO. This makes it more odd so many people route through one place.

Throwing in Japan into random topics in trains feel somewhat unfair. Most train fact sheets fail to include most Asian nations except Japan, often missing even Korea and Taiwan. Commuter trains in many East/Southeast Asian cities like Shanghai has developed to levels comparable to Tokyo. Trains in some Central Asian cities such as Mumbai were also always notorious for congestions. I think those should also be considered more often and at greater depths, Fermi estimated if need be, than we would be just keep dropping random Shinjuku facts left and right.

  Is India considered central Asia? I've always seen it referred to as south Asia, and former Soviet countries like Kazakhstan have been referred to as central Asia. I think India is east of these "central Asian" countries. Perhaps this is all a bit of pedantry.

    I was mistaken, I meant to say South Asia. Central was more like north of India/China...
    - kaladin-jasnah 1y ago
      Ah, I see. I was curious since I guess you can refer to it as central Asia since it's west of east Asia, haha.

  We have stats for India, and they're no match: Kolkata Howrah gets about 1M pax per day, Mumbai CST around 670k. Nothing to sneeze at, but still several million (!) less than Shinjuku. China has numerous airport-sized stations that handle huge volumes of long-distance passengers, but I'm not aware of any single commuter hub remotely the size of Shinjuku. Partly this is because of the economic system: Chinese trains are all state-run and centralized, while a large part of why Shinjuku is so busy is that it's a hub for numerous private railways as well.

    > I'm not aware of any single commuter hub remotely the size of Shinjuku There certainly isn't one that does the volume of passengers. Shanghai Hongqiao or Beijing South are probably busiest, and they're 3-4x less passengers than Shinjuku. > Partly this is because of the economic system: Chinese trains are all state-run and centralized, while a large part of why Shinjuku is so busy is that it's a hub for numerous private railways as well. I think another part of it is also size of network. China is a freaking huge country. It's got like 10-15x as much high speed rail track compared to Japan. It's a lot more distributed.

If only 1% give money to homeless people, that’s… a good place to beg for money. I would probably make more there than what i make at my fancy software engineering job (100K before taxes per year): - 36000 people - let’s say each give 10 cents ($) - that’s $3600 per day - if you beg 8h per day, that’s $1200/day - begging mon to fri means $24000 per month (tax free)

  This assumes there is a central entrance you can situate yourself as a beggar. In reality there are probably 10+ entrances.

  With 28800s in 8 hours that's more than 1 donation per second during these 8 hours. Also you now have 36000 10ct coins, that's more than 100kg in coins to move every day
- initramfs 1y ago
  very unrealistic because many train riders don't carry coins, nor will use a contactless payment to pay a random begger, even if they see them on the platform every day.

  This is hilarious, thank you

    Leave it to HN to gamify begging.

  Begging is illegal in Japan.

I’m really impressed at how usable that visualisation is on mobile. It’s also really great aesthetically. Japanese artists can still do the best sci fi designs about

Yeah that makes Exit 8 looks like Child's play Saint-Lazare being the most complex one that I saw personally (got lost, I mean)

Is this actually to scale? If so, do the near-vertical moving dashed lines depict inclined lifts or escalators? Because they look very steep when you compare them to other metro escalators, such as those in the Brussels Metro's Porte de Hal / Hallepoort station[1], which seem closer to 50° from horizontal.

- robertlutece 1y ago
  I believe the floors have been pulled further apart to help with navigating around the model which would also steepen the escalators.
wkat4242 1y ago
It looks like the vertical distances are greatly exaggerated though, making it look bigger than it is. Nice work still
